DOOR-FASTENING.

T 0 all whom t may concern.'

Be it known that I, REED PEOR, of Cortlandville, in the county of Cortland and State of New York, have invented a new and useful Improvement in Fastenings for Folding Doors for Barns and other Buildings; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure l, is a descriptive view of a pair of folding doors, with a fastening standard attached. Fig. 9., is a perspective view of the fasteningstandard and its gearing, de` tached from the door. Fig. 3, is a detached perspective view of aspring or latch, which in connection with the gearing holds the standard in position and properly adjusted while the door to which it is attached is open.

Similar letters of reference indicate corresponding parts in each of the several figures.

My improvement in fastenings for doors, consists in a certain'adjustment of the fastening standard by means of gearing, combined with a spring or latch, rendering the standard self fastening from its force of gravity, at the moment the door is brought to its place in shutting.

To enable others to make and use my invention I will now proceed to describe its construction and operation.

In Fig. l, which is a descriptive view A, B, represents the fastening standard which is made in two parts. Each part of the standard should be made about two inches wide and one and a half inches thick of hard wood. The longer part (A,) of the standard should extend nearly the whole length of the door. rlhe shorter part (13,) should extend from the top of the door down by the side of the longer part, to a point three or four inches below the lower edge of the upper batten, C, and both parts secured by clasps a, a, a. The clasps a, a, a, may be made of heavy hoop iron and fastened to the door with wood screws. The

clasps should be made sufficiently large to allow the standard to slide in them easily. The edges of the two part-s of the standard are rabbeted on the back side at Z), B, (see Fig. 2) and a cast iron rack c, about three inches long is secured by screws in the rabbeting of each. The racks should be far enough from the inside edges of the two parts of the standard to admit the pinion d, between them without crowding them apart.

The pinion Z should be one inch in diameter, with cogs corresponding with the cogs in the racks. The pinion (cl) turns on a pivot which passes through the door at d, and is secured on the outside by a nut or otherwise. By making the standard in two parts, and connecting them by gearing as described, it will be readily perceived that any movement of the longer part of the standard, up or down, will give to the .shorter part a corresponding movement in the opposite direction, so that when the door is closed and fastened at the top and bottom, to open it, it is only necessary to raise the longer part of the standard out of the mortise in the oor, (7), the shorter part will at the same time be drawn down and out of the mortise at the top of the door.

The spring or latch shown in Fig. 3 eX- tends from the top of the door to near the middle of the upper batten (c) and is secured to it by screws. It is placed behind the shorter part of the standard. Near the top of the spring is a lip a projecting about one inch under which the short part of the standard rests while the door is open. The spring should always be placed on the door, so as to bring the lip under and close to the beam at the top of the door. The top of the spring should rest against the beam when the door is shut or closed.

It will be seen at once, that when the longer part of the standard is raised for the purpose of unfastening the door, the shorter part (B) will be drawn down and the spring or latch will at the same moment catch the top of the standard and in connection with the gearing, hold the whole properly adjusted for fastening the door should it be closed by the wind or otherwise. In closing the door, the top of the spring strikes the beam before the door gets to its place, and as the door is carried along, the lip on the spring is drawn from the top of the standard at the right point, when by its force of gravity, the standard securely fastens the door at the top and bottom.

The other door D, should be fastened with a common spring latch of a large size or something equivalent thereto and in that ease it would be immaterial which door is closed first, as the door to which the standard is attached will fasten both whenever it comes to its place.

In the adjustment of self fastening gravitating standards to doors I do not wish to confine myself to the use of toothed gearing and spring for the same results may be obtained by means of pulleys, friction rollers, spiral springs, &c.

Making the standard in two parts I do not claim as new for it has been so made before, and the parts connected by a lever with the fulcrum between them, but this mode is objectionable as the lever throws the parts of the standard far apart, and
